Description

Technical Field

[0001] The utility model relates to the technical field of temperature control equipment, and particularly relates to a passive temperature control device. Background Art

[0002] With the continuous progress of society, people have put forward higher requirements in addition to the basic functions of buildings - safety, comfort and durability, among which mobility and variability are particularly crucial. Mobile and variable buildings, due to their unique flexible transfer characteristics and variable and comfortable building spaces, show broad application potential in multiple fields such as outdoor desert environments, emergency disaster relief, urban and rural public services, community services, and home travel. Taking the application in computer rooms as an example, especially in generator rooms, a large amount of heat is generated during operation. Traditionally, it mainly relies on reasonable ventilation and air conditioning systems to maintain a good thermal and humid environment inside, such as using a cooling method mainly based on ventilation supplemented by a local air conditioning system, or a thermal and humid environment control means and equipment mainly based on an air conditioning system supplemented by a fresh air system for heat dissipation. However, this heat dissipation method has obvious drawbacks: due to the air circulation, dust in the external environment of the computer room is easily inhaled, resulting in dust accumulation on the internal equipment of the computer room, which not only affects the performance of the equipment but may also cause failures.

[0003] In high-temperature desert areas, this problem is particularly prominent. The environmental temperature in desert areas is extremely high, up to over 50°C, which poses extremely high challenges to the heat dissipation system of the computer room. At the same time, due to the compact layout of the internal equipment in the generator room, the ventilation effect is limited. In the existing design of generator rooms, although the enhancement of ventilation and heat dissipation effects has been considered, due to the limitation of the ventilation area, it is still difficult to achieve the expected heat dissipation effect.

[0004] Therefore, the technical research on heat dissipation and dust prevention for houses in the above different fields is particularly important. It is necessary to explore new heat dissipation methods to effectively control the temperature inside the house and at the same time effectively prevent the entry of dust. Especially in high-temperature desert areas, it is more necessary to consider how to design a device that can effectively dissipate heat and prevent dust in combination with the local environmental characteristics.

[0006] The technical solution of the present utility model is a passive temperature control device, including a temperature control component and a temperature control space. The temperature control component is fixedly connected to the temperature control space. The temperature control component includes a phase change plate made of a phase change material.

An air passage for communicating with the outside air is provided in the heat exchange space, and a ventilation mechanism for opening or closing the air passage is provided in the air passage.

[0007] Further, the temperature control space is a closed space formed by a heat insulation layer, and the heat insulation layer is made of a heat insulation material to prevent the outside temperature from being transmitted to the inside of the temperature control space.

[0008] Further, the whole isolation layer is composed of a phase change plate.

[0009] Further, the ventilation mechanism includes fans arranged at the air inlet end and the air outlet end of the air passage, hinge baffles arranged in a sealed manner at the air inlet end and the air outlet end, and electric telescopic rods are arranged between the hinge baffles and the connections at the air inlet end and the air outlet end.

[0010] Further, dust-proof nets are respectively installed at the air inlet end and the air outlet end of the air passage.

[0011] Further, the temperature control component is also provided with an electronic control module and a temperature detection module for detecting the temperature of the temperature control space and the external environment. The electronic control module is electrically connected to the fan, the electric telescopic rod of the hinge baffle and the temperature detection module respectively.

[0012] Further, the temperature control space is also provided with a solar power supply system for supplying power to the equipment inside the temperature control space. The solar power supply system is at least composed of a solar panel, a solar controller, an inverter and a storage battery. The solar panel is arranged above the temperature control space and is electrically connected to the input end of the solar controller through the positive and negative poles of a cable. The solar controller is electrically connected to the storage battery to transmit direct current into the storage battery for charging. The storage battery is electrically connected to the inverter, and the inverter converts the direct current into alternating current for the equipment inside the temperature control space to use.

[0013] Further, the phase change plate is fixedly connected to the temperature control space through a connection structure and arranged in the isolation layer.

[0014] Furthermore, the connection structure is a hoisting connection structure. The phase change board is fixedly connected to the top of the temperature control space through the hoisting connection structure. The hoisting connection structure includes a suspension rod, a transverse keel, a longitudinal keel, and a connecting piece. The transverse keel is fixedly connected to the top of the temperature control space through the suspension rod. A connection groove is provided at the top of the transverse keel. One end of the connecting piece is fixedly connected to the longitudinal keel, and the other end is slidably clamped in the connection groove of the transverse keel. The phase change board is fixedly connected to the transverse keel. The interiors of the transverse keel and the longitudinal keel are hollow, and through holes for ventilation are evenly distributed on both sides.

[0015] Furthermore, the connection structure is a wall connection structure. The phase change board is fixedly connected to the inner side of the temperature control space through the wall connection structure. The wall connection structure includes a wall bracket and a connection component. The connection component includes a magnet attachment.

[0016] The utility model has the following beneficial effects: The temperature control component in the present invention can play the roles of heat storage and cooling, and at the same time can reduce the air flow in the temperature control space to prevent dust from entering the temperature control space. By the characteristic that the phase change material can absorb a large amount of latent heat during the phase change process from solid state to liquid state, when the external temperature is relatively high during the day, the air channel is closed, so that the air in the heat exchange space cannot circulate with the outside world, thereby preventing the external heat from entering the temperature control space and playing a good heat insulation role. The phase change board can absorb a large amount of heat generated by the equipment in the temperature control space, thereby reducing the temperature in the temperature control space. At the same time, since the air in the temperature control space does not circulate, it can effectively prevent the external heat and dust and other sundries from entering the temperature control space through the air flow. And when the external temperature is relatively low at night, the air channel is opened, and the fan is used to accelerate the air flow in the air channel, quickly bringing the low-temperature air outside into the heat exchange space. At this time, the phase change board cools down, such as from liquid state to solid state, and releases the stored heat. The low-temperature air outside passes through the air channel to dissipate heat from the heat exchange space and takes away the heat released by the phase change board to the outside, so that the phase change board can maintain the phase change state of heat absorption and continuously absorb the heat generated by the equipment in the temperature control space, thereby ensuring that the equipment in the temperature control space can work at an appropriate temperature and will not be damaged due to overheating.

Detailed implementation manners

[0024] The following will clearly and completely describe the concept, specific structure and technical effects generated by the present utility model in combination with the embodiments and drawings, so as to fully understand the purpose, scheme and effects of the present utility model.

[0026] In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present application. The terms used in the description of the present specification are only for describing specific embodiments, rather than for limiting the present utility model. The term "and / or" used herein includes any combination of one or more of the related listed items.

[0027] It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from each other. For example, without departing from the scope of the present disclosure, the first element may also be referred to as the second element, and similarly, the second element may also be referred to as the first element.

[0028] As shown Figures 1 to 6 in the figure, the present utility model provides a passive temperature control device, which includes a temperature control component and a temperature control space 1. The temperature control component is fixedly connected to the temperature control space 1. The temperature control component includes a phase change plate 2 composed of a phase change material. The phase change material (PCM - Phase Change Material) can change its physical state within a certain temperature range. Taking the phase change from solid state to liquid state as an example, or from liquid state to solid state. This phase change process is accompanied by the absorption or release of a large amount of latent heat. A heat exchange space 3 is provided outside the temperature control space 1 and separated by an isolation layer. The phase change plate 2 is arranged in the isolation layer. The isolation layer can be selected to be completely composed of the phase change plate 2 according to actual situations, or combined with other plates and only partially composed of the phase change plate 2 to achieve the above functions. The isolation layer seals and separates the temperature control space 1 and the heat exchange space 3, so as to prevent dust and the like from entering the temperature control space during the process of heat exchange between the heat exchange space 3 and the outside air.

[0029] The phase change plate 2 is arranged at the top and / or the inner side inside the temperature control space 1. As Figure 1 shown in Embodiment 1 of the present utility model, when arranged at the top of the temperature control space 1, it forms a ceiling. As Figure 2In the second embodiment of the present utility model, a wall is formed on the inner side of the temperature control space 1. An air passage for communicating with the outside air is provided in the heat exchange space 3, and a ventilation mechanism for opening or closing the air passage is provided in the air passage. The ventilation mechanism can be an air inlet end and an air outlet end respectively arranged at both ends of the air passage. The ventilation mechanism includes a flap baffle 5 and a fan 4. The fan 4 is arranged in the air inlet end and the air outlet end. The flap baffle 5 is hinged to the upper ends of the air inlet end and the air outlet end. An electric telescopic rod 6 is further arranged between the flap baffle 5 and the air inlet end and the air outlet end. Both ends of the electric telescopic rod 6 are hinged to the flap baffle 5 and the air inlet end and the air outlet end respectively. Due to the characteristic that the phase change material can absorb a large amount of latent heat during the phase change process from solid state to liquid state, when the outside temperature is relatively high during the day, the air passage is closed, so that the air in the heat exchange space 3 cannot communicate with the outside, thereby preventing the outside heat from entering the temperature control space 1 and playing a good heat insulation role. The phase change material in the phase change plate 2 absorbs a large amount of heat generated by the equipment in the temperature control space 1 and gradually undergoes a phase change from solid state to liquid state, thereby reducing the temperature in the temperature control space 1. At the same time, since the air in the temperature control space 1 does not circulate, it can effectively prevent the outside heat and dust and other sundries from entering the temperature control space 1 through the air circulation, thereby effectively avoiding the adverse effects of dust on the equipment. And when the outside temperature is relatively low at night, the air passage is opened, and the fan 4 is used to accelerate the air flow in the air passage, and the low-temperature air outside is quickly brought into the heat exchange space 3. At this time, since the temperature is lower than the phase change temperature of the phase change material in the phase change plate 2, the phase change material gradually undergoes a phase change from liquid state to solid state and releases heat to the heat exchange space 3. The low-temperature air outside dissipates heat to the heat exchange space 3 through the air passage and takes away the heat dissipated by the phase change plate 2 to the outside. Since internal equipment such as a generator room needs to work continuously, the heat generated by the equipment causes the temperature in the temperature control space 1 to rise continuously, seriously affecting the operating environment of the equipment. Therefore, it is necessary to select an appropriate phase change plate 2 that can maintain the endothermic phase change state and continuously absorb the heat generated by the equipment in the temperature control space 1, so as to ensure that the equipment in the temperature control space 1 can work at an appropriate temperature and will not be damaged due to overheating.

[0030] Such as Figure 1 And Figure 2As shown, dust-proof nets 7 are respectively installed at the air inlet end and the air outlet end of the air channel. The dust-proof nets 7 are made of fine fiber materials and have good air permeability and filtering effect. The dust-proof nets 7 are fixedly installed inside the air inlet end and the air outlet end. By providing the dust-proof nets 7, dust, insects and other impurities can be prevented from entering the heat exchange space 3 from the outside, and the air circulation will not be hindered. At the same time, since if dust and other impurities enter the heat exchange space 3, they may adhere to the phase change plate 2, affecting its heat exchange efficiency and service life. Therefore, the presence of the dust-proof nets 7 not only prevents dust but also protects the phase change plate 2, enabling it to work more persistently and effectively. In addition, since there is a dust-proof net 7 at the place where heat is exchanged with the outside, the isolation layer between the temperature control space 1 and the heat exchange space 3 can be set to be unsealed, and devices such as exhaust fans can be provided at the isolation layer to further extract the heat in the temperature control space.

[0031] As Figure 4 As shown, the temperature control component is also provided with an electronic control module 8 and a temperature detection module 9 for detecting the ambient temperature of the temperature control space 1. The electronic control module 8 is electrically connected to the fan 4, the electric telescopic rod 6 of the movable baffle 5 and the temperature detection module 9 respectively. The temperature detection module 9 is a high-precision temperature sensor, which is respectively installed at appropriate positions in the temperature control space 1 and the outside to accurately detect the ambient temperatures of the temperature control space 1 and the outside. Among them, the temperature detection module 9 arranged in the temperature control space 1, when the temperature detection module 9 detects that the temperature of the temperature control space 1 is higher or lower than the set comfortable temperature range, it will transmit this signal to the electronic control module 8. After receiving the signal, the electronic control module 8 will judge whether it is necessary to adjust the working state of the temperature control device according to the preset logic. If necessary, the electronic control module 8 will send instructions to the fan 4 and the electric telescopic rod 6 of the movable baffle 5 to control their switches or adjust their working states to achieve the temperature adjustment of the temperature control space 1. Through the cooperation of the electronic control module 8 and the temperature detection module 9, the temperature control device can achieve intelligent temperature control, automatically adjust the temperature of the temperature control space 1 without manual intervention, and improve the comfort of the operation of the internal equipment in the temperature control space 1.

[0032] As Figure 3As shown, the temperature-controlled space 1 is also equipped with a solar power supply system for powering the internal equipment of the temperature-controlled space 1. The solar power supply system consists of at least a solar panel 10, a solar controller 11, an inverter 12, and a storage battery 13. The solar panel 10 is generally installed above the temperature-controlled space 1, such as on the roof, etc., to maximize the reception of solar radiation. And through the positive and negative poles of the cable being electrically connected to the input end of the solar controller 11, the solar controller 11 is electrically connected to the storage battery 13 to transmit direct current into the storage battery 13 for charging. The storage battery 13 is electrically connected to the inverter 12, and the inverter 12 converts direct current into alternating current for the internal equipment of the temperature-controlled space 1 to use. The solar power supply system makes full use of renewable energy, significantly reduces the dependence on traditional electric energy, thereby reducing carbon emissions and achieving the goal of green energy conservation. The power storage function of the storage battery 13 enables the temperature-controlled space 1 to maintain a certain power supply even when there is no power supply outdoors, grid failure, or power outage, enhancing the emergency response ability.

[0033] In addition, according to the complexity and specific requirements of the solar power supply system, the solar power supply system may also include some other auxiliary devices or components. For example, a photovoltaic array support: used to support and fix the solar panel 10 to ensure it receives solar radiation at the best angle; a DC combiner box: in the solar power supply system, the DC combiner box is used to collect the direct current generated by multiple solar panels 10 for subsequent processing and transmission. A DC distribution cabinet: used to distribute DC electric energy to ensure that the electric energy flows to each load or inverter 12 along a predetermined path. An AC distribution cabinet: in a grid-connected or distributed system, the AC distribution cabinet is used to distribute the alternating current converted by the inverter 12 to meet the power consumption needs of different loads. An electricity meter: used to measure key parameters such as the power generation and power consumption of the solar power supply system, which helps monitor the operation status of the system and conduct energy efficiency analysis. Grid connection equipment: in a grid-connected solar power supply system, grid connection equipment needs to be configured to achieve interconnection with the public grid. These devices may include an inverter 12, an isolation transformer, etc. A power supply system monitoring device: used to monitor the operating parameters of the solar power supply system in real time, such as voltage, current, power, etc., as well as the charge and discharge status of the storage battery 13. An environmental monitoring device: used to monitor the parameters of the environment where the solar power supply system is located, such as light intensity, temperature, humidity, etc. A lightning protection and grounding device: in areas with frequent lightning strikes, in order to prevent lightning from damaging the solar power supply system, a lightning protection and grounding device needs to be configured. These devices can effectively introduce lightning into the ground to protect the system from lightning strikes.

[0034] According to the above technical features, in a specific embodiment, the passive temperature control device of the present utility model is applied to a residence located in a hot area. The temperature control space 1 is of a common brick-concrete structure or precast slab house structure. The temperature control components are installed on the top and all inner walls of the house, forming part of the ceiling and walls. The phase change board 2 is made of a material that can undergo a phase change in the temperature range of 20°C to 30°C, which is exactly the comfortable temperature range of the temperature control space 1. The air inlet end and the air outlet end 4 at both ends are respectively located at the highest point of the ceiling and the bottom of the wall, and are equipped with dust-proof nets 7 and electric control ventilation mechanisms.

[0035] The solar power supply system is installed on the roof of the house, including a high-efficiency monocrystalline silicon solar panel 10, an MPPT solar controller 11, a pure sine wave inverter 12, and a large-capacity lithium battery. The area of the solar panel 10 is 20 square meters, which can meet the daily power consumption needs of all equipment inside the house, and the surplus power is stored in the storage battery 13 for use at night or on cloudy days.

[0036] The working principle in this specific embodiment:

[0037] 1. Daytime temperature control and heat insulation: When the outside temperature is higher than a preset temperature such as 30°C, the temperature detection module 9 detects a high-temperature signal, and the electric control module 8 automatically closes the air passage, for example, by closing the hinge baffle 5, and stops the fan 4 from running. At this time, the outside heat cannot enter the heat exchange space 3, and the static air layer in the heat exchange space 3 effectively prevents the outside heat from being transferred to the temperature control space 1 by air convection. Preferably, the temperature control space 1 is composed of heat insulation materials or covered with a heat insulation layer composed of heat insulation materials on the outside, so that the outside heat cannot enter the temperature control space 1 by means of transfer. Heat insulation materials are materials that can block the heat flow, also known as thermal insulation materials. Traditional thermal insulation materials, such as glass fiber, asbestos, rock wool, silicate, etc., and new thermal insulation materials, such as aerogel felt, vacuum panel, etc. The phase change material in the phase change board 2 absorbs a large amount of heat generated by the equipment in the temperature control space 1 and gradually undergoes a phase change from solid to liquid, thereby reducing the temperature in the temperature control space 1.

[0038] 2. Night temperature control: When the outside temperature drops to the preset temperature such as below 20°C, the temperature detection module 9 sends a low-temperature signal, and the electric control module 8 drives the movable baffle 5 to open the air channel and starts the fan 4. The low-temperature outside air is inhaled into the heat exchange space 3 through the air channel, causing the low-temperature outside air to flow through the phase change board 2, accelerating the process of the phase change board 2 changing from a liquid state to a solid state, for example, and taking away the stored heat dissipated by the phase change board 2 to the outside, so that the phase change board 2 can maintain the form of absorbing heat in the solid state and continuously absorb the heat generated by the equipment in the temperature control space 1. At the same time, since the phase change board 2 composed of a phase change material is selected for temperature control, the air exchange between the temperature control space 1 and the outside is avoided, effectively blocking dust and other sundries from entering the temperature control space 1 through air exchange.

[0039] 3. Solar power supply: In places such as the desert wilderness where it is impossible to connect to the mains for power supply, during the day, the solar panel 10 collects solar energy and converts it into direct current, which charges the battery 13 through the solar controller 11. At night or on cloudy days, the electrical energy in the battery 13 is converted into alternating current through the inverter 12 and supplied to the electrical equipment in the temperature control space 1, including the fan 4 of the temperature control device and the electric control system, realizing green energy conservation.

[0040] Such as Figure 5The following shows the third embodiment of the connection structure in the present utility model: When the phase change plate 2 is arranged on the top of the temperature control space 1 to form a ceiling, the phase change plate 2 is connected and fixed to the temperature control space 1 through a connection structure. The connection structure is a hoisting connection structure. The phase change plate 2 is connected and fixed to the top of the temperature control space 1 through the hoisting connection structure. The hoisting connection structure includes a suspender 14, a transverse keel 15, a longitudinal keel 16 and a connector 17. The transverse keel 15 is connected and fixed to the top of the temperature control space 1 through the suspender 14. A connection groove 18 is provided at the top of the transverse keel 15. One end of the connector 17 is connected and fixed to the longitudinal keel 16, and the other end is slidably clamped in the connection groove 18 of the transverse keel 15. The phase change plate 2 is connected and fixed to the transverse keel 15. The connection between the phase change plate 2 and the top of the temperature control space 1 adopts a hoisting connection structure. This structure realizes the stable hoisting of the phase change plate 2 through multiple components such as the suspender 14, the transverse keel 15, the longitudinal keel 16 and the connector 17. The suspender 14, as the main supporting component of the hoisting connection structure, is firmly connected to the top of the temperature control space 1 at one end and is connected to the transverse keel 15 at the other end, providing a stable supporting force for the entire hoisting structure. The transverse keel 15 is designed with a connection groove 18. The connection groove 18 not only enhances the structural strength of the keel but also provides convenience for subsequent installation and connection. One end of the connector 17 is tightly connected to the longitudinal keel 16, and the other end is slidably clamped in the connection groove 18 of the transverse keel 15. This not only ensures the firm connection between the longitudinal keel 16 and the transverse keel 15 but also allows for fine adjustment within a certain range to adapt to different installation requirements. The phase change plate 2 is firmly combined with the top of the temperature control space 1 by being connected and fixed to the transverse keel 15. Both the transverse keel 15 and the longitudinal keel 16 are designed with a hollow interior, and through holes 19 for ventilation are evenly distributed on both sides. This design not only reduces the weight of the keel and the installation difficulty but also provides a good ventilation environment for the phase change plate 2, which helps to improve its temperature control effect.

[0041] The temperature control space 1 can be an enclosed space such as a chassis box for placing equipment and a house, which is used to cool and control the temperature of the equipment inside the enclosed space. The phase change plate 2 can be fixed at the corresponding position of the chassis box through a clamping structure. The structure of the chassis box will not be described in detail here.

[0042] Such as Figure 6The following is the fourth embodiment of the connection structure in the present utility model: When the phase change plate 2 is arranged inside the temperature control space 1, and the temperature control space 1 is a house and forms a wall, the phase change plate 2 is connected and fixed to the temperature control space 1 through a connection structure, and the connection structure is a wall connection structure. The phase change plate 2 is connected and fixed to the inner side of the temperature control space 1 through the wall connection structure. The wall connection structure includes a wall bracket 20 and a connection component. The connection component includes a magnet attachment 21. The magnet attachment 21 is fixedly arranged on one side of the phase change plate 2. The wall bracket 20 is vertically arranged on the wall of the temperature control space 1. The phase change plate 2 is adsorbed and fixed on the wall bracket 20 through the magnet attachment 21. The connection between the phase change plate 2 and the inner side of the temperature control space 1 adopts a wall connection structure. This structure mainly consists of two major parts, namely the wall bracket 20 and the connection component. The core of the connection component is the magnet attachment 21. The wall bracket 20 is vertically installed on the wall of the temperature control space 1. As a support structure, it provides a stable attachment point for the phase change plate 2. The magnet attachment 21 is fixed on one side of the phase change plate 2. By using the adsorption effect of magnetic force, the phase change plate 2 is firmly adsorbed on the wall bracket 20. When installing the phase change plate 2, just bring it close to the wall bracket 20, and the magnet attachment 21 will automatically adsorb on the bracket, thus realizing the rapid and convenient installation and maintenance of the phase change plate 2. When it is necessary to maintain or replace the phase change plate 2, just remove it from the wall bracket 20, and the operation is simple and fast.

[0043] The phase change plate 2 is fixed to the temperature control space 1 through a hoisting connection structure and a wall connection structure. The hoisting connection structure uses a suspension rod 14, a transverse keel 15, a longitudinal keel 16 and a connector 17 to ensure that the phase change plate 2 is stably suspended on the roof. The wall connection structure easily adsorbs the phase change plate 2 on the wall bracket 20 through the magnet attachment 21, which is convenient for installation and maintenance. The internal hollow design of the transverse keel 15 and the longitudinal keel 16, as well as the distributed through holes 19, further enhance the ventilation effect of the heat exchange space 3 and optimize the temperature control performance.
